An intragastric balloon robot is a less invasive and effective method for morbid obesity treatment. Traditional balloon robots need insertion tools and endoscopes for placement and removal of balloons in the stomach, which may cause complications such as nausea and sickness. This paper proposes a novel capsule robot for obesity treatment with wireless powering and communication.…
CA-SVM: Communication-Avoiding Support Vector Machines on Distributed Systems
We consider the problem of how to design and implement communication-efficient versions of parallel support vector machines, a widely used classifier in statistical machine learning, for distributed memory clusters and supercomputers. The main computational bottleneck is the training phase, in which a statistical model is built from an input data set. Prior to our study, the…
Synchrony in neuronal communication: An energy efficient scheme
We are interested in understanding the neural correlates of attentional processes using first principles. Here we apply a recently developed first principles approach that uses transmitted information in bits per joule to quantify the energy efficiency of information transmission for an inter-spike-interval (ISI) code that can be modulated by means of the synchrony in the…
Evaluation of Vehicle-to-Vehicle Communication with Delay Tolerant Networks for Safety Surveillance System
Recently, the rapid technological growth of automobiles expects us to the various usages for the near future, and V2V communication is also a part of novel technologies to realize novel usages as well as ITS. This paper proposes the V2V communication with Delay Tolerant Networks (DTN) for safety surveillance system in the local area during the winter season. In…
Distributed traffic simulation using DDS-communication based HLA for V2X
For implementing Cooperative Intelligent Transport Systems (C-ITS), Vehicle-to-X (V2X)communication functions are important. For efficient V2X simulation, integrating heterogeneous simulators and sophisticated inter-simulator network control are required. In this paper, we suggest Data Distribution Service (DDS) communication-based High Level Architecture (HLA) for distributed V2X simulation by replacing HLA network transport into DDS-based communication. For replacing, we design HLA-DDS wrapper…
Software-defined wireless mesh networks: architecture and traffic orchestration
SDN has been envisioned as the next generation network paradigm by decoupling control plane and data plane, such that network management and optimization can be conducted in a centralized manner using global network information. In this article, we study how to apply SDN concept to a wireless meshnetwork that has been widely adopted by various applications. We first propose a novel architecture…
EXR: Greening Data Center Network with Software Defined Exclusive Routing
The explosive expansion of data center sizes aggravates the power consumption and carbon footprint, which has restricted the sustainable growth of cloud services and seriously troubled data center operators. In recent years, plenty of advanced data center network architectures have been proposed. They usually employ richly-connected topologies and multi-path routing to provide high networkcapacity. Unfortunately, they also undergo…
Control-plane slicing methods in multi-tenant software defined networks
In this paper, we focused on two prevailing architectural approaches for control-plane virtualization in multi-tenant OpenFlow-ready SDN domains: The first permits the delegation of a specific, non-overlapping part of the overall flowspace to each tenant OpenFlow controller, exposing him/her the entire substrate topology; the second conceals the substrate topology to tenants by abstracting resources and…
Active probing assisted monitoring for software defined networks
Efficient and agile control-plane design is crucial for emerging flexible, on-demand optical networks. Active probing assisted monitoring is proposed and shown to reduce monitoring time by around 75% to achieve rapid monitoring in optical networks.
Demonstrating a software defined network (SDN) using Carrier Ethernet Switch Routers in a provider network
We demonstrate SDN in a service provider network using adapted Carrier Ethernet Switch Routers developed based on principles of segment routing. SDN based service composition and delivery is showcased and validated.
